HORIZONTAL SAWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 420,348, dated January28, 1890.

Application filed July 11, 1889. $eria1No. 317,190. (No model.) Patentedin England March 16, 1889, N0. 4,6 38.

To all whom it may concern.-

Be it known that I, FREDERICK ROBBINS LANE, engineer, a subject of theQueen of G1 eat Britain, residing at Woodborough, in the county of\Viltshire, England, have invented certain Improvements in HorizontalSawin g-Machines, (for which I have previously obtained Letters Patentin Great Britain, dated March 16, 1889, No. 4,638,) of which thefollowing is a full, clear, and exact description.

This invention relates to steam, gas, or water power horizontalsaw-frames, the object of the improvement being to render such framesportable byconstructing them in a number of parts, which may be readilydetached for transport and re-erected when re- ,quired; and it alsorelates to the driving mechanism, with the object of simplifying themechanical arrangements for reciprocating the saw with comparatively n0vibration and less power required, the saw being capable of beingreciprocated at a much higher speed, and thereby doing a larger amountof sawing, also enabling it to cut veneers.

In the accompanying drawings, Figure 1 represents a front elevation of ahorizontal sawing-machine constructed according to my invention; Fig. 2,a plan view thereof; Fig. 3, an end elevation, and Fig. 4 a partialsection taken through line as an on Fig. 1.

Referring first to the construction of the structural frame, Arepresents two rails or sleepers, which may be of either wood or metal,and which are laid on or sunk into the ground at a suitabledistanceapart in a direction at right angles to the line of the saw. Astoutbeamof timber B is supported by these sleepers, and is mortised. toward eachend to receive the tenoned ends of two vertical posts C, the upper endsof the .posts being surmounted by metal caps O,

tal beam B, and the other two of each set connect the caps O to whichthey are attached, respectively, to the ends of the rails A, whichsupport the said beams.

The saw E is mounted in a rectangular metal frame composed of twovertical pieces E, connected by nuts e to the two horizontal rods E thesaw being stretched between the lowerends of the pieces E by means ofthe usual clamps e and nuts e To the vertical pieces E are screwed or'bolted slide-blocks E, which are free to work in slides F, fixed to thesaddle G, which slides upon the posts 0 on the slides 0 and can beraised or lowered by means of the screws H, which work through nuts h,attached by brackets h to the saddle G, and are squared at their upperends to receive a screw-key or spanner or other suitable gearing.

The driving mechanism consists of a disk J, mounted on a shaft J',whichworks in bear- 7o ings formed. on or attached to the saddle G.

The shaft J also carries fast and loose pulleys K, for the driving-beltL to travel around,

anda fly-wheel M. On the face of the disk J is a swivel-stud j, whichworks within a yoke formed by two vertical bars N, which are bored attheir ends, so as to slide upon the rods E of the rectangular metalframe,

being kept at a suitable distance apart by collars n and clamped by nutsn The rods E, as will be observed, are thickened in their middleportions, such thickened portions being screw-threaded. By thisarrangement the nuts a can slide over the end portions of the rods E,and thus a considerable amount of screw-threading is dispensed with. Itwill be obvious that as the disk J rotates, the stud j, actingalternately on each side of the yoke N, will impart a reciprocatorymotion to the rectangular frame, and consequently to the 0 saw E, theextent of such motion depending on the distance of the stud j from thecenter of the disk J. The material to be fed to the saw is mount;

ed on one or more trolleys running on rails and worked by chain-feed orother suitable form of gearing.

Vention,WhatI claim as new, and desire to sedescribed, and illustratedin the accompanycure by Letters Patent, is ing drawings.
